Haifeng Polyurethane Machinery is an industrial supplier focused on polyurethane (PU) equipment manufacturing and system solutions. Zhejiang Haifeng Automation Equipment Co., Ltd. operates the brand in global markets.
1. Industries and services
Haifeng’s equipment serves B2B industrial customers such as footwear factories, sponge-foaming plants, insulation-panel manufacturers, cold-chain container and rigid-foam product manufacturers, and automotive-interior and composite-material companies. Applications span automotive and transportation, leather, footwear, home furnishings, electronics packaging, construction, and sports and leisure manufacturing. Haifeng also serves specialized industrial applications such as rail transit, composites (glass fiber or carbon fiber with PU) and precision coating for adhesive tape.
Typical applications and solutions by industry:
| Industry | Typical Applications | Customer Challenges | Haifeng Solution and Benefits |
| Footwear | Sports and safety shoe soles | Traditional bonding may fail, and production efficiency is low | One-piece dual-density direct-injection molding. Haifeng is the sole drafting organization for the industry standard in this field |
| Home furnishings | Sofa cushions, mattresses and backrests | Inconsistent flexible-foam production | Continuous foaming equipment improves material utilization and product consistency |
| Automotive and transportation | Steering wheels, headrests, armrests and cushioning blocks | High resilience and integral-skin processes have demanding requirements | Casting solutions have been validated in applications such as automotive cushioning blocks and high-speed-rail vibration-damping pads |
| Construction | Waterproofing membranes and floor coatings | Compliance pressure from low-VOC environmental standards | Solvent-free coating machines can keep VOCs below 50 g/L |
Digital management modules
Haifeng integrates IoT and data analytics into production management. Key modules include:
Predictive maintenance: Uses equipment operating data to flag potential faults and reduce unplanned downtime.
Quality traceability: Allows each product batch to be traced back to its process parameters and operating records.
Process data analysis: Optimizes key parameters such as casting temperature and mixing ratio to improve finished-product yield.
Remote collaboration: Supports remote commissioning and troubleshooting, reducing overseas service costs.
Access control: Applies tiered access to equipment parameters and production data to support industrial security.
2. Main products
Haifeng’s product portfolio covers multiple stages of polyurethane processing:
PU foaming machines and low- and high-pressure PU foaming equipment:
The equipment incorporates independently developed multi-component proportioning control technology, with key-component metering accuracy maintained around ±0.3%.
High-pressure foaming models feature a high-speed mixing head and a precision water-circulation heating system. They rapidly emulsify the raw materials and control reaction heat, helping eliminate residual bubbles and produce a fine, uniform cell structure with a soft, resilient feel.
Polyurethane sole machines (direct-injection molding machines):
These machines produce single- or dual-color polyurethane soles in a one-step direct-injection molding process. High-precision servo metering pumps and a proprietary closed-loop pressure and flow-control algorithm keep metering accuracy around ±0.3%, minimizing weight variation among soles in the same batch. High-pressure mixing heads provide sufficient shear to prevent localized over-foaming or “hard-core” defects and help produce a uniform, dense cell structure with a soft, resilient feel.
PU spraying equipment:
Designed for high precision and efficiency across different production environments, the equipment uses intelligent precision controls. The spraying process avoids entrained bubbles and distributes foaming material evenly throughout the mold. Integrated six-axis robotic spraying follows three-dimensional paths to coat complex surfaces precisely. Uniform mixing, stable operation, automated spraying and efficient production help achieve a smooth, even, bubble-free coating while improving material utilization and cycle time.
Continuous sponge-foaming and continuous sandwich-panel production lines:
Designed for the sponge-foaming and insulation-panel industries, these lines use a highly integrated, coordinated control system that centralizes control points at a main control center. This enables coordinated line-wide parameter control and fault self-diagnosis. Precision temperature and flow-control systems help ensure uniform cell structure, good foam resilience and a fine feel, meeting the demanding consistency requirements of large-scale continuous production.
Complete polyurethane plant solutions: Haifeng provides turnkey lifecycle services covering engineering design, equipment procurement, construction and project operations. Drawing on proven experience serving more than 1,200 customers worldwide, Haifeng tailors solutions from individual machines to complete production lines. IoT-integrated lines can help customers improve production efficiency by more than 30% and increase product yield to approximately 96%. Haifeng supports customers from pre-sales process consultation and pilot trials through complete-line delivery under an EPC+M+O model. Offices at the Wenzhou headquarters, Foshan and Gaomi, Shandong, form a 24-hour response network.
3. Company positioning
Haifeng focuses on B2B industrial equipment, providing global manufacturers with stable and efficient polyurethane production equipment. Its systems cover the full process chain, from raw-material foaming to finished-product forming. Haifeng specializes in non-standard customization and complete-line integration based on each customer’s capacity, workshop layout and process requirements. Its technical system, supported by 51 patents and multiple software copyrights, enables seamless transitions among casting, dispensing, molding, foaming and injection processes. Nearly 40 years of continued development around industrial requirements have built a lifecycle service system spanning solution design, installation and commissioning, and spare-parts supply.
